To all whom 'it may concern:

Be it known thatI, AMAND' BU'ssn, a lcitizen of the United States, and a resident of the city of- New York, borough of the Bronx in the county and State-'of York,.lhave invented a new andlI-mpr'oved Metal-Frame for Glass Panes, of which the following is a full, clear, and exact description. A ,f

The invention is an improvement in metal frames for glass panes, such as windows, doors, green-houses, etc., and belongs to that class of such constructions in which the mullions and transonis are formed of intersecting T-bars continuous in length.

The object of the invention is to -provide a frame of this character in which no bulging or upsetting of the nietal is necessary at the front of the frame, to bring the flanges or heads of the bars into the same plane in order that the glass panes may bear fiat against the 'inner faces of both the mullions and transoins.

Reference is to be had to the accompanying drawings forming a pait of lthis specilication, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is an outside face view, partly in section, of 4a frame constructed in accordance showing the panes in with my invention, place; Fig. 2 is a cross-section of the frame; Fig. is a cross-section of the frame on an enlargedscale, taken at the points of intersectionl of the traiisoins with the inullions;

Fig. 4 is a' similar longitudinal section; Fig.

Fig. 6 is an outer face view of one of the transoins; Fig. 7 is a plan of one of the transoins; Fig. 8 is a viewsimilar to Fig. 4, showing a modified form of construction; and Fig. 9 is a fragmentary sectional view of the frame shown in Fig. 8.

The frame as constructedconsists of metal inullions 10 and intersecting metal transoms 11, each continuous in length and in'the form of a T-bar, with the heads of the mullion bars provided with ribs 10a centrally varranged on their outer `faces to give the frame sufficient strength and ri idity as well as add to the ornamentation o the co In that form of the invention shown in Figs. 1 to'5 inclusive, thewebs ofthe mul- T-slots 12, through New mullions at the ends of the slots.

indicated at 147 one of the inullions;

are seated which the transoms pass, the heads ofthe slots being arranged adjacent to the heads or flanges ofthe mullions; and slits 13 are formed longitudinally iii the webs of the points of intersection of the iiiullions andA transoms the heads of the bars of which the latter are formed are transversely cut out as and best 'shown in Figs. 6

and '7, the width of the cut-ont portions being approximately-equal to the width of the heads of the niullion bars.

In assembling the inullions and transoms, the metal at the inner side of therslitsvl is* forced or bnlged from the web of the mullion bars `suiliciently to permitof the transoms being slid through. Then the removed or cnt-out portions 14 in the heads of the transoins are in place opposite the prop er At the.l 6o

inullions, the bulged portions ofthe iiiullion The transom and 89' The construction shown in the left-hand portion of Fig. 8 and that shown in Fig.l 9A is in all respects the saine as that described, except the slots 12a in the mullions, corresponding to .the slots 12, are length ing the webs'of the mullions. The transoms `l in this construction 'are forced forwardly to bring and secure the heads thereA of suflcient 90 to receive the transoms without bulg- A of in a plane with the heads of the mullions,

by driving in keys 16, the keys beingV inserted in the slotsv ack of the inner vedges of the transom webs. Inv either vconstruction the fra-nie presents an unbroken inislied appearance at the front and the panes of glass the inner faces of the flat 'against their complete width heads of the bars for and length.

-In the construction sliownat therighthand end of Fig. S', the head of the transom bar l1 bears against the inner face of the vhead of the inullion bar 10, in which 4case the 4heads vof the two sets of bars are not located in the saine plane,

frame thus the rear of the other.v -With the f cut-out portions T-bar,

constructed a liner of some character should be placed between the glass panes and the inner faces of the outwardly-arranged heads in order to provide a bearing for the edges of the panes along these lines.

Having thus described my invention, I claim as new and desireV tosecure by Letters Patent:

l. The combination of intersecting mullions and transoms, eachin the form of a with the bars extending in one direction having T-slots in the webs thereof, through which the intersecting bars pass, and with the head of one of the bars at each point of intersection cut out to receive the head of the other bar and thus locate the heads of all the bars in the same plane.

2. The combination of a series of mullions, and a transom intersecting the mullions, the transom and mullions each being 'in the form of a T-bar, with the mullon hars having T-slots in the webs thereof, through which the transom passes, and the transom bar having the heads thereof removed to receive .the heads of the mullion bars.

v3. The combination of intersecting mullions and transoms, each inthe form of a metal T-bar continuous in length, one set of said bars'having T-slots passing through the Awebs thereof, with a slit formed in the web at the end of each slot, and the other set of bars received in said slots and having in the heads at the points of intersection-to receive the heads of the other bars, and with the bars having the cutout portions engaged at the inner end and secured in place bythe metal at the inner side of the slits. v-

4. The herein-described process ofjoining metal T-bar mullions and transoms, which consists in providing the webs of one set of the bars with T-slots of less length than the maximum width of the other bars, and with slits at the inner ends of the slots, eX- panding the metal at the inner sides of the slots sufficiently to admit of the other set of bars being slid endwise through the slots, providing the other set of bars with cutout portions adapted to register with the first set of bars and forcing the expanded metal inwardly to securethe two sets of bars together when the cut-out portions of the second set of bars are in register with the lirst set of bars.

5. The combination of a mullion-bar and a transom-bar intersecting each other, each bar having a head and a web, with one of the bars at the point of intersection having a slot in the web thereof through which the other bar is adapted to be slid when both of the bars are facing in the same direction, and the other bar having its head cut out at the point of intersection to receive the head of the slotted bar and thus locate the heads of both of the bars in the same plane.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
